How GitHub Copilot Could Steer Microsoft Into a Copyright Storm (theregister.com) 83

An anonymous reader quotes a report from the Register: GitHub Copilot -- a programming auto-suggestion tool trained from public source code on the internet -- has been caught generating what appears to be copyrighted code, prompting an attorney to look into a possible copyright infringement claim. On Monday, Matthew Butterick, a lawyer, designer, and developer, announced he is working with Joseph Saveri Law Firm to investigate the possibility of filing a copyright claim against GitHub. There are two potential lines of attack here: is GitHub improperly training Copilot on open source code, and is the tool improperly emitting other people's copyrighted work -- pulled from the training data -- to suggest code snippets to users?

Butterick has been critical of Copilot since its launch. In June he published a blog post arguing that "any code generated by Copilot may contain lurking license or IP violations," and thus should be avoided. That same month, Denver Gingerich and Bradley Kuhn of the Software Freedom Conservancy (SFC) said their organization would stop using GitHub, largely as a result of Microsoft and GitHub releasing Copilot without addressing concerns about how the machine-learning model dealt with different open source licensing requirements.

Copilot's capacity to copy code verbatim, or nearly so, surfaced last week when Tim Davis, a professor of computer science and engineering at Texas A&M University, found that Copilot, when prompted, would reproduce his copyrighted sparse matrix transposition code. Asked to comment, Davis said he would prefer to wait until he has heard back from GitHub and its parent Microsoft about his concerns. In an email to The Register, Butterick indicated there's been a strong response to news of his investigation. "Clearly, many developers have been worried about what Copilot means for open source," he wrote. "We're hearing lots of stories. Our experience with Copilot has been similar to what others have found -- that it's not difficult to induce Copilot to emit verbatim code from identifiable open source repositories. As we expand our investigation, we expect to see more examples. "But keep in mind that verbatim copying is just one of many issues presented by Copilot. For instance, a software author's copyright in their code can be violated without verbatim copying. Also, most open-source code is covered by a license, which imposes additional legal requirements. Has Copilot met these requirements? We're looking at all these issues."
GitHub's documentation for Copilot warns that the output may contain "undesirable patterns" and puts the onus of intellectual property infringement on the user of Copilot, notes the report.

Bradley Kuhn of the Software Freedom Conservancy is less willing to set aside how Copilot deals with software licenses. "What Microsoft's GitHub has done in this process is absolutely unconscionable," he said. "Without discussion, consent, or engagement with the FOSS community, they have declared that they know better than the courts and our laws about what is or is not permissible under a FOSS license. They have completely ignored the attribution clauses of all FOSS licenses, and, more importantly, the more freedom-protecting requirements of copyleft licenses."

Brett Becker, assistant professor at University College Dublin in Ireland, told The Register in an email, "AI-assisted programming tools are not going to go away and will continue to evolve. Where these tools fit into the current landscape of programming practices, law, and community norms is only just beginning to be explored and will also continue to evolve." He added: "An interesting question is: what will emerge as the main drivers of this evolution? Will these tools fundamentally alter future practices, law, and community norms -- or will our practices, law and community norms prove resilient and drive the evolution of these tools?"

DeepMind Breaks 50-Year Math Record Using AI; New Record Falls a Week Later (arstechnica.com) 30

Last week, DeepMind announced it discovered a more efficient way to perform matrix multiplication, conquering a 50-year-old record. This week, two Austrian researchers at Johannes Kepler University Linz claim they have bested that new record by one step. Ars Technica reports: In 1969, a German mathematician named Volker Strassen discovered the previous-best algorithm for multiplying 4x4 matrices, which reduces the number of steps necessary to perform a matrix calculation. For example, multiplying two 4x4 matrices together using a traditional schoolroom method would take 64 multiplications, while Strassen's algorithm can perform the same feat in 49 multiplications. Using a neural network called AlphaTensor, DeepMind discovered a way to reduce that count to 47 multiplications, and its researchers published a paper about the achievement in Nature last week.

To discover more efficient matrix math algorithms, DeepMind set up the problem like a single-player game. The company wrote about the process in more detail in a blog post last week. DeepMind then trained AlphaTensor using reinforcement learning to play this fictional math game -- similar to how AlphaGo learned to play Go -- and it gradually improved over time. Eventually, it rediscovered Strassen's work and those of other human mathematicians, then it surpassed them, according to DeepMind. In a more complicated example, AlphaTensor discovered a new way to perform 5x5 matrix multiplication in 96 steps (versus 98 for the older method).

This week, Manuel Kauers and Jakob Moosbauer of Johannes Kepler University in Linz, Austria, published a paper claiming they have reduced that count by one, down to 95 multiplications. It's no coincidence that this apparently record-breaking new algorithm came so quickly because it built off of DeepMind's work. In their paper, Kauers and Moosbauer write, "This solution was obtained from the scheme of [DeepMind's researchers] by applying a sequence of transformations leading to a scheme from which one multiplication could be eliminated."

DeepMind's Game-Playing AI Has Beaten a 50-Year-Old Record In Computer Science (technologyreview.com) 91

An anonymous reader quotes a report from MIT Technology Review: DeepMind has used its board-game playing AI AlphaZero to discover a faster way to solve a fundamental math problem in computer science, beating a record that has stood for more than 50 years. A year after it took biologists by surprise, AlphaFold has changed how researchers work and set DeepMind on a new course. The problem, matrix multiplication, is a crucial type of calculation at the heart of many different applications, from displaying images on a screen to simulating complex physics. It is also fundamental to machine learning itself. Speeding up this calculation could have a big impact on thousands of everyday computer tasks, cutting costs and saving energy.

Despite the calculation's ubiquity, it is still not well understood. A matrix is simply a grid of numbers, representing anything you want. Multiplying two matrices together typically involves multiplying the rows of one with the columns of the other. The basic technique for solving the problem is taught in high school. But things get complicated when you try to find a faster method. This is because there are more ways to multiply two matrices together than there are atoms in the universe (10 to the power of 33, for some of the cases the researchers looked at).

The trick was to turn the problem into a kind of three-dimensional board game, called TensorGame. The board represents the multiplication problem to be solved, and each move represents the next step in solving that problem. The series of moves made in a game therefore represents an algorithm. The researchers trained a new version of AlphaZero, called AlphaTensor, to play this game. Instead of learning the best series of moves to make in Go or chess, AlphaTensor learned the best series of steps to make when multiplying matrices. It was rewarded for winning the game in as few moves as possible. [...] The researchers describe their work in a paper published in Nature today. The headline result is that AlphaTensor discovered a way to multiply together two four-by-four matrices that is faster than a method devised in 1969 by the German mathematician Volker Strassen, which nobody had been able to improve on since. The basic high school method takes 64 steps; Strassen's takes 49 steps. AlphaTensor found a way to do it in 47 steps.
"Overall, AlphaTensor beat the best existing algorithms for more than 70 different sizes of matrix," concludes the report. "It reduced the number of steps needed to multiply two nine-by-nine matrices from 511 to 498, and the number required for multiplying two 11-by-11 matrices from 919 to 896. In many other cases, AlphaTensor rediscovered the best existing algorithm."

Can a Fork Save Cutefish OS (or Its Desktop)? (debugpoint.com) 109

In April ZDNet called its beta "the cutest Linux distro you'll ever use," praising the polished "incredible elegance" of Debian-based Cutefish OS, with its uncluttered, MacOS-like "Cutefish DE" desktop.

But now CutefishOS.com times out, with at least one Reddit user complaining "their email is not responding" and seeking contributors for a fork.

But meanwhile, the technology site DebugPoint.com shares another update: It looks like the OpenMandriva project is already continuing with the development of the Cutefish DE (not the OS) for its own OS. For more details, visit the Matrix discussion page.

Besides, it's worth mentioning that Arch Linux already have the Cutefish desktop packages in the community repo. You can even install it as a standalone desktop environment in Arch Linux with easy steps. As you can see, it is easier to maintain the desktop environment to continue its development because the structure is already out there.

I have tested and reviewed hundreds of distros for years, and Cutefish OS is the promising one with its stunning desktop environment. It was written from the ground up with QML and C++ and took advantage of KWin. It would have been an attractive desktop as a separate component and could have been another great option besides KDE Plasma or GNOME.

Many open-source projects are born and die every year, and it's unfortunate to see the situation of Cutefish OS. I hope an official fork comes up soon, and we all can contribute to it.

Thunderbird 102 Released (thunderbird.net) 35

slack_justyb writes: Thunderbird 102 has been released with some new UI improvements and new features. There has been a change in the icons, the layout of the address book has been upgraded to feature a more modern UI, and a new UI feature known as the spaces toolbar to get around Thunderbird. New features include an updated import and export wizard, a UI for editing the email header settings, and Matrix client support within Thunderbird, which is a messaging system using HTTPS that is similar to Discord if you've used that.

Finally, the Thunderbird Twitter account released the first screenshot of the new UI that is being targeted for the 114 release. For those wondering what the Thunderbird team has done and is doing, you can always head over to the planning section of the developer site. The roadmap are things they're working on the current release and the backlog are the things they are working towards.

Samsung To Close LCD Business (koreatimes.co.kr) 44

An anonymous reader quotes a report from The Korea Times: Samsung Display has decided to close its liquid-crystal display (LCD) business in June, hobbled by a declining global competitive edge due to cheaper products made by its Chinese and Taiwanese counterparts, according to the industry, Sunday. No investment plan details have since been announced. The decision by the display affiliate of Samsung Group came six months sooner than expected, due in large part to rapid losses from falling LCD prices. According to Display Supply Chain Consultants (DSCC), a U.S. market research firm, the average price index of LCD panels, measured against 100 in January 2014, will fall to 36.6 in September of this year. The figure has dropped farther from the record low of 41.5 in April of this year, and 58 percent lower than the record high of 87 in June 2021.

Samsung Display will no longer produce LCDs used for large TV screens and focus instead on manufacturing organic light-emitting diode (OLED) and quantum dot (QD) displays. The employees of the LCD businesses are expected to be transferred to the QD businesses. The display affiliate was first formed in 1991, as an LCD business arm under Samsung Electronics. It formally launched in 2012 as Samsung Display and has since merged with three local and Japanese makers of active matrix organic light-emitting diodes (AMOLED), for the production of advanced types of displays.

As Far as China Is Concerned, Keanu Reeves No Longer Exists (msn.com) 149

"It's no longer possible to watch any content starring Keanu Reeves in China," reports PC Magazine, "and searching for his name returns no results from search engines."

The AV Club explains: Earlier this year, about a month after the release of The Matrix Resurrections, Reeves was announced as a performer at the 35th annual Tibet House Benefit Concert. The concert was organized by Tibet House, a nonprofit founded by supporters of the Dalai Lama that Chinese authorities have labeled "a separatist organization advocating for Tibetan independence," according to The Hollywood Reporter....

Now, after his appearance at the show, it's being reported by the Los Angeles Times that the Matrix movies, Speed, Bill & Ted's Excellent Adventure, The Lake House, and more films from the actor's catalog can no longer be streamed on platforms such as Tencent Video, Youku, and Migu Video.... The one Reeves picture that is still up and available to stream in the country is Toy Story 4 — but that's because the film's credits feature the dubbing cast, not the original cast from the American release.

But it's more than that, notes PC Magazine: As Reuters reports, the Chinese authorities have seemingly wiped the actor's existence from servers across the country.... And with the internet being so restricted and controlled there, it's relatively simple for those in power to digitally disappear someone. So far, Tencent and iQiyi have removed at least 19 of the actor's movies from their streaming platforms, and performing a search for either his English name or its Chinese translation will return zero results from search engines, apparently.
The Los Angeles Times supplies some context: The development emerged just after his latest film "The Matrix: Resurrections" became the first blockbuster to hit Chinese theaters in over two months, ending an unusually prolonged drought of censorship approvals on U.S. titles in a year of rising geopolitical tensions and a further cooling of relations with Hollywood.... "It's a curious case that's worth following. We tend to think of the censorship machine in China as this really coordinated monster, but the fact that we're seeing these conflicting signals [between the online and theatrical markets] suggests that some of these measures come from different places," said Alex Yu, a researcher at China Digital Times, a U.S.-based news organization that translates and archives content censored in China.

It's unclear who ordered the deletions, China's regulatory agencies or platforms acting proactively to remove potentially troublesome content, Yu said.... "Why all of a sudden did they decide to take this measure at this exact moment? It's a question we as outsiders might never be able to answer," Yu said. "The system is so opaque that it's pretty much impossible to pinpoint which agency or person is responsible...."

The ban on Reeves' past works bodes poorly for the China prospects of his upcoming projects. These include animation "DC League of Super-Pets," starring Chinese fan favorite Dwayne Johnson, and the pandemic-delayed sequel "John Wick: Chapter 4," which appears to target mainland viewers with its top billing of Donnie Yen, the Hong Kong action star known for his expressions of loyalty to China's ruling Communist Party....

Despite the original trilogy's popularity, "The Matrix: Resurrections" was a flop in China even before it faced nationalist backlash, grossing only $13.6 million and notching just 5.7 out of 10 on the taste-making ratings platform Douban.

The US Will Finally Allow Adaptive Beam Headlights on New Cars (arstechnica.com) 177

The National Highway Traffic Safety Administration is finally poised to legalize adaptive beam headlights in the US. From a report: The NHTSA announced that it has issued a final rule that will update the Federal Motor Vehicle Safety Standards, which currently only allow for "dumb" high- and low-beam lights. Adaptive beam lights use a matrix of projectors, some of which can be turned off to shape the beam so the lights illuminate the road but don't shine at an oncoming driver. (These are an advancement over the auto-high beam technology that you may have fitted to your current car.) The technology has been around for nearly two decades in Europe and Japan.

Harvard Mathematician Proves 150-Year Old Chess Puzzle (popularmechanics.com) 30

joshuark shares a report from Popular Mechanics: A mathematician from Harvard University has (mostly) solved a 150-year-old Queen's gambit of sorts: the delightful n queens puzzle. In newly self-published research (meaning it has not yet been peer-reviewed), Michael Simkin, a postdoctoral fellow at Harvard's Center of Mathematical Sciences and Applications, estimated the solution to the thorny math problem, which is based loosely on the rules of chess. The queen is largely understood to be the most powerful piece on the board because she can move in any direction, including diagonals. So how many queens can fit on the chess board without falling into each other's paths? The logic at play here is similar to a sudoku puzzle, dotting queens on the board so that they don't intersect.

Picture a classic chess board, which is an eight-by-eight matrix of squares. The most well-known version of the puzzle matches the board because it involves eight queens -- and there are 92 solutions in this case. But the "n queens problem" doesn't stop there; that's because its nature is asymptotic, meaning its answers approach an undefined value that reaches for the infinite. Up until now, experts have explicitly solved for all the natural numbers (the counting numbers) up to 27 queens in a 27-by-27 board. However, there is no solution for two or three, because there's no possible positioning of queens that satisfies the criteria. But what about numbers above 27?

Consider this: for eight queens, there are just 92 solutions, but for 27 queens, there are over 200 quadrillion solutions. It's easy to see how solving the problem for numbers higher than 27 becomes extremely unwieldy or even impossible without more computing power than we have at the moment. That's where Simkin's work enters the arena. His work approached the topic through a sharp mathematical estimate of the number of solutions as n increases. Ultimately, he arrived at the following formula: (0.143n)n. In other words, there are approximately (0.143n)n ways that you can place the queens so that none are attacking one another on an n-by-n chessboard.

DARPA Flies a Black Hawk Helicopter Without a Pilot For 30 Minutes (cnet.com) 81

The Defense Advanced Research Projects Agency has flown a UH-60A Black Hawk helicopter without a pilot for the first time ever. CNET reports: DARPA's Aircrew Labor In-Cockpit Automation System program was used to fly the helicopter on autopilot over Fort Campbell, Kentucky, on Saturday. The Black Hawk was kitted out with Sikorsky Matrix autonomous flying technology, and DARPA says it repeated the "uninhabited flight" on Monday. "Pilots can focus on mission management instead of the mechanics," Stuart Young, program manager in DARPA's Tactical Technology Office, said in a statement. "ALIAS ... includes the ability to operate aircraft at all times of the day or night, with and without pilots, and in a variety of difficult conditions, such as contested, congested, and degraded visual environments."

Is 'The Matrix Resurrections' a Critique of the Tech Industry - or Society? (politico.com) 187

When The Matrix Resurrections premiered in San Francisco, the city's mayor "celebrated the appearance of her fair city in the film and cheered the film's economic contributions to the region," reports SFGate. "But there's a problem of aesthetics at play here... It is undeniably a dystopian hellscape where police rule the city and technology looms over all..." In the first section of the movie, the metaphor of the Matrix mirrors that of the tech industry depicted in the film. Tech is stereotypical here — lots of T-shirt-wearing men playing ping-pong and talking about how to design the next great video game. The most annoying character in the film, Jude (Andrew Caldwell), is a proxy for all annoying tech bros...
Meanwhile Politico writes that the original 1999 film The Matrix actually "changed politics, almost entirely by mistake," and calls the new Matrix Resurections "a sophisticated self-critique of the culture that swallowed it." In the past two decades, the idea of a "red pill" has taken on a life of its own in American culture, most prominently at first in an infamous misogynist subreddit, and then more broadly as a symbol of any kind of political awakening, almost always on the right. The idea has proliferated wildly throughout politics, and especially the darkest ideological corners of the internet, in which to be "red-pilled" means to realize that American society has been hopelessly debased by liberals, requiring a total rethink of its premises... Hugo Weaving, who memorably portrayed the original films' villain, lamented in a 2020 interview how people "will take something that they think is cool and they will repurpose it to fit themselves when the original intention or meaning of that thing was quite the opposite...." [T]he Wachowskis have been largely silent about the "meaning" of their creation — a movie franchise that not only became a ubiquitous cultural phenomenon, but predicted the cultural tenor of politics in the digital age with an eerie, oracular accuracy. We know they got it right, but what did they think about it?

Wednesday saw the release of "The Matrix Resurrections," a long-delayed sequel from one of the original writer/directors (Lana directed; Lilly sat it out) — and also an answer to that question. As a movie, it's everything its predecessors was, an impressive feat of visual-effects artistry, action choreography and original sci-fi worldbuilding. But even more, it's a two hour and 27-minute-long piece of cultural criticism. The film interrogates, to a jarringly specific degree, not just its own iconography, but how American culture has evolved around and bastardized it over the past two decades. "The Matrix Resurrections" is both wildly successful popcorn entertainment and a window into a long-misunderstood creative mind. But in refitting its entire premise to the social media age, it illustrates just how much the contours of American society have changed in the intervening decades....

The original "Matrix" was deeply of its time. Reeves' Neo a was a quintessential late 1990s corporate drone, captive to the professional ennui also depicted in films of the era like "Fight Club" and "Office Space." Its modern incarnation is a cry of protest against something else: society's willingness to trade individual agency for the neurological reward pellets of the Online. Visual metaphors abound, with Reeves disoriented by a procession of mirrors that serve as gateways to another world, another possible truth. "Your brain is hooked on this shit the Matrix has been feeding you for years," one character tells him. "They don't know you like I do.

"I know exactly what you need...."

The movie is streaming now on HBOMax for subscribers in their $15 ad-free tier — but, like, Dune, only during its 31-day theatrical run.

The US Car Rental Market is Crying Out for Disruption (theatlantic.com) 117

Supply is low, demand is high -- but that alone cannot explain the weird indignity of renting a vehicle. From a report: The present situation is "the most challenging in the history of car rental," says Chris Brown, the digital editor of the industry trade publication Auto Rental News. "Last year ... it was a disaster." Nobody could have planned for such a catastrophic revenue loss, he told me, and while the airline industry received a government bailout, the rental-car industry did not. "Hertz had 3,000 cars burned to the ground because someone lit a match, and they just burned in a field," he added. (Something like this did happen in Florida, though only around 1,000 of the 4,500 cars destroyed in the fire belonged to Hertz, and investigators blamed the episode on a hot exhaust pipe and dry grass.) Given the context, some negative customer experiences were to be expected, Brown argued. "But I think it's really impressive how car-rental [companies have] been able to pull themselves out of this very difficult time managing as well as they are."

Well, I'm not trying to be unfair to any companies, but many car-rental businesses did receive funds from the Paycheck Protection Program. And many of their negative customer experiences have nothing to do with a car shortage or a pandemic. Why is that car-rental employee typing for so long? We'll never know. Why are the printers so old and loud and broken? Who could say! Will you ever get a straight answer as to how much insurance to buy, or whether to prepay for gas, or why it's forbidden for you to drive this rental car out of the state of Florida? What does the pandemic have to do with Avis allegedly repossessing a rental car from someone's driveway in the middle of the night in Teaneck, New Jersey, and then allegedly claiming to know absolutely nothing about it, in one of the oddest stories I have ever read? And what does the pandemic have to do with the stream of complaints about rental-car companies on the Better Business Bureau website, a surprising number of which come from people who insist that they do not smoke yet they have been charged as much as $450 for allegedly smoking in a car?

I reached out with questions of this kind to the three largest rental-car companies, which control the large majority of the rental-car business in the United States. Enterprise Holdings did not respond. Avis Budget declined to comment about either the state of the industry or the alleged incident in Teaneck. A Hertz spokesperson said, in part, "Hertz is working closely with our automotive partners to add new vehicles to our fleet as quickly as possible amid the microchip shortage that continues to impact the car rental industry. We're also purchasing low-mileage, pre-owned vehicles, and moving vehicles to the areas with highest demand." The financial structure of these companies is as inscrutable as a contract printed on a dot-matrix printer and signed in a dim underground parking garage. Some of them have gone bankrupt; at least one has done so multiple times. Take Hertz for instance: Private-equity firms acquired the company from Ford in 2005, then made a profit of $1 billion with an IPO while the company itself remained deeply in debt. The company is also on its sixth CEO since 2014 and has been deemed a "Frankenstein of financial engineering" by Axios. Most of the cars that Hertz rents out are owned by "special-purpose" subsidiaries of Hertz, from which Hertz then leases them. When Hertz was sliding into bankruptcy in spring 2020, it was because the company had missed lease payments -- to put it crudely -- to itself. I can barely understand this, yet I will walk into a rental-car office and suffer for it.

'The Matrix' Changed Visual Effects. Now 'Resurrections' Pivots To Reality. (wsj.com) 48

While 1999 movie influenced everything from videogames to action movies to the metaverse, latest installment shows some restraint. From a report: The jaw-dropping visual effects in "The Matrix" transformed the quest to prove what is possible on screen. The franchise returns this week to find out if there is anything more that can be done. For the 1999 original, filmmakers invented a way to make Keanu Reeves's hero, Neo, defy physics while dodging bullets on screen. The effect blew enough minds to get a nickname -- "bullet time" -- plus changed the look of action movies, and influenced mediums from animation to videogames. For the new sequel, "The Matrix Resurrections," filmmakers deployed much-higher-caliber technologies, including three-dimensional imagery made using artificial intelligence. But after 22 years of digital evolution, high-end movie effects are approaching a plateau near perfection. "We went from pulling off what seemed to be impossible, to a sort of inability to create surprise" in the movie industry, says John Gaeta, who helped craft the bullet-time effect. He was a visual-effects designer on the first three "Matrix" films; now he is making things for the metaverse.

This year the movies presented us with a car slingshotting from cliff to cliff ("F9"); Ryan Reynolds running amok inside a videogame ("Free Guy"); and giant monsters crushing the Hong Kong skyline ("Godzilla vs. Kong"). Any viewers who paused to ask themselves -- "How did they do that?" -- likely came up with the same answer: "Computers." Human characters that are totally computer-generated and believable are still on the frontier, "but I'm not sure if there is anything else that can't be done given enough money or time," says Ian Failes, editor of befores and afters, a magazine covering visual-effects artistry. Despite any numbness among viewers to digital spectacles, Hollywood's demand for them has only increased. Visual-effects houses have raced to compete in a global production boom and fuel the streaming wars with flashy content. Some directors are reacting to the VFX arms race by practicing more restraint. Denis Villeneuve's "Dune" depicts settings such as the desert planet Arrakis with a naturalistic look. Instead of zooming viewers into a fleet of attacking space ships, the director presented the nighttime ambush in silhouette at a distance, conveying a somber sense of scale. "He was just showing the reality of the world," says Namit Malhotra, chief executive of DNEG, a visual-effects company that worked on "Dune" and "The Matrix Resurrections." He adds: "When you're spending that kind of money, it's hard for filmmakers to control the desire for more, a little more oomph."

In the new "Matrix" release, director and co-writer Lana Wachowski plays with expectations that the sequel must level up. Spoiler alert: In the movie, Mr. Reeves's character is reintroduced as a videogame designer whose big hit was called, yes, "The Matrix." The events in the film franchise supposedly happened within the world of his videogame -- including that signature action sequence in which Neo bends time and space. As a group of videogame developers brainstorm ideas for a sequel to "The Matrix," one declares, "We need a new bullet time!" The original bullet time was "a borderline hack," as Mr. Gaeta recalls it, that started with 120 still cameras firing off film photographs of Mr. Reeves dangling on wires. Those images were stitched together with software to simulate a swooping camera move in slow motion. The successor to that technique is known as volumetric capture. A camera array captures people or spaces from every angle, and then A.I. meshes this video into 3-D footage that can be viewed and manipulated from any perspective.

Researchers Teach Human Brain Cells In a Dish To Play 'Pong' (futurism.com) 44

Slashdot reader Hmmmmmm quotes a report from Futurism: Researchers at the biotechnology startup Cortical Labs have created "mini-brains" consisting of 800,000 to one million living human brain cells in a petri dish, New Scientist reports.

The cells are placed on top of a microelectrode array that analyzes the neural activity... To teach the mini-brains the game, the team created a simplified version of "Pong" with no opponent. A signal is sent to either the right or left of the array to indicate where the ball is, and the neurons from the brain cells send signals back to move the paddle...

Brett Kagan, chief scientific officer at Cortical Labs and research lead of the project, said that while the mini-brains can't play the game as well as a human, they do learn faster than some AIs.

"The amazing aspect is how quickly it learns, in five minutes, in real time," he told New Scientist. "That's really an amazing thing that biology can do."

While this is certainly some amazing Twitch fodder, the team at Cortical Labs hope to use their findings to develop sophisticated technology using "live biological neurons integrated with traditional silicon computing," according to their website.

There's actually video of the brain cells playing Pong. The chief scientific officer told New Scientist that when the cells are in the game, they actually believe they are the paddle.

"We often refer to them as living in the Matrix."

Wind Power Becomes Spain's Leading Energy Source for 2021 (elpais.com) 89

An anonymous reader shares a report: Even if the wind stops blowing in the next three weeks, wind power will end the year as the leading source of electricity in Spain. This will mean wind overtaking nuclear in the national energy matrix for the first time since 2013, the only year since records began in which wind turbines were the main source of power. That year was particularly good in terms of wind resources while nuclear was affected by the closure of the Garoña plant in Burgos. Since then, however, wind power has continued to grow as a percentage of total energy generated both in absolute and relative terms, a trend that looks to continue in the near future. The milestone, advanced by Spanish news site Nius, is just a taste of things to come. "Wind power is going to dominate the Spanish electricity grid for a long time," says Francisco Valverde, a consultant at the energy company Menta Energia.

According to the National Integrated Energy and Climate Plan (PNIEC), released by the Spanish government last year, the installed capacity of wind turbines will almost double between now and 2030. During this period, the rate of growth of solar photovoltaic will be even greater as installed capacity more than quadruples, making it the second most important electricity source, though it will still lag far behind wind power, even when solar thermal is taken into account. Meanwhile, installed nuclear power will fall to less than half its current level. And both combined-cycle plants, which use natural gas, and hydroelectricity will maintain their weight in a mix in which coal will no longer be included.

'Matrix' Stars Discuss Free 'Matrix Awakens' Demo Showing Off Epic's Unreal Engine 5 (theverge.com) 34

This year's Game Awards also saw the premiere of The Matrix Awakens, a new in-world "tech demonstrator" written by Lana Wachowski, the co-writer/director of the original Matrix trilogy and director of the upcoming sequel. It's available free on the PS5 and Xbox Series X/S, reports the Verge, and they also scored a sit-down video interview with Keanu Reeves and Carrie-Ann Moss about the new playable experience — and the new Matrix movie: Reeves also revealed that he thinks there should be a modern Matrix video game, that he's flattered by Cyberpunk 2077 players modding the game to have sex with his character, and why he thinks Facebook shouldn't co-opt the metaverse.

Apart from serving as a clever promotion vehicle for the new Matrix movie premiering December 22nd, The Matrix Awakens is designed to showcase what's possible with the next major version of Epic's Unreal Engine coming next year. It's structured as a scripted intro by Wachowski, followed by a playable car chase scene and then an open-world sandbox experience you can navigate as one of Epic's metahuman characters. A big reason for doing the demo is to demonstrate how Epic thinks its technology can be used to blend scripted storytelling with games and much more, according to Epic CTO Kim Libreri, who worked on the special effects for the original Matrix trilogy...

Everything in the virtual city is fully loaded no matter where your character is located (rather than rendered only when the character gets near), down to the detail of a chain link fence in an alley. All of the moving vehicles, people, and lighting in the city are generated by AI, the latter of which Libreri describes as a breakthrough that means lighting is no longer "this sort of niche art form." Thanks to updates coming to Unreal Engine, which powers everything from Fortnite to special effects in Disney's The Mandalorian, developers will be able to use the same, hyper-realistic virtual assets across different experiences. It's part of Epic's goal to help build the metaverse.

Elsewhere the site writes that The Matrix Awakens "single-handedly proves next-gen graphics are within reach of Sony and Microsoft's new game consoles." It's unlike any tech demo you've ever tried before. When we said the next generation of gaming didn't actually arrive with Xbox Series X and PS5, this is the kind of push that has the potential to turn that around....

Just don't expect it to make you question your reality — the uncanny valley is still alive and well.... But from a "is it time for photorealistic video game cities?" perspective, The Matrix Awakens is seriously convincing. It's head-and-shoulders above the most photorealistic video game cities we've seen so far, including those in the Spider-Man, Grand Theft Auto and Watch Dogs series... Despite glitches and an occasionally choppy framerate, The Matrix Awakens city feels more real, thanks to Unreal Engine's incredible global illumination and real-time raytracing ("The entire world is lit by only the sun, sky and emissive materials on meshes," claims Epic), the detail of the procedurally generated buildings, and how dense it all is in terms of cars and foot traffic.

And the most convincing part is that it's not just a scripted sequence running in real-time on your PS5 or Xbox like practically every other tech demo you've seen — you get to run, drive, and fly through it, manipulate the angle of the sun, turn on filters, and dive into a full photo mode, as soon as the scripted and on-rails shooter parts of the demo are done. Not that there's a lot to do in The Matrix Awakens except finding different ways to take in the view. You can't land on buildings, there's no car chases except for the scripted one, no bullets to dodge. You can crash any one of the game's 38,146 drivable cars into any of the other cars or walls, I guess. I did a bunch of that before I got bored, though, just taking in the world.... Almost 10 million unique and duplicated assets were created to make the city....

Epic Games' pitch is that Unreal Engine 5 developers can do this or better with its ready-made tools at their disposal, and I can't wait to see them try.

A Plan To Perfect the New York City Street (curbed.com) 70

An "achievable, replicable" plan for a city that's embracing public space as never before. Curbed: New York and Curbed recruited a team of designers and consultants, led by the architecture firm WXY, to approach the streets as a matrix of overlapping, interrelated networks. The allure of more humane cities has generated an entire library's worth of plans and pilot projects, both top-down and grassroots, for areas like Downtown Brooklyn and Soho. A few years ago, a consortium of Harlem business and organizations collaborated on a plan to redesign East 125th Street. In 2019, the City Council passed a law requiring the Department of Transportation to develop a five-year citywide plan. But this torrent of good intentions and expertise has fragmented the issue further by producing more schemes to ignore, postpone, and gripe about. Most New Yorkers' concerns are exquisitely parochial: The only time a Bronxite is likely to care about, say, the width of Soho's sidewalks is if it makes parking there even worse.

So we tried to imagine what a comprehensive transformation would produce on a generic Manhattan block, to the extent that one exists. We chose Third Avenue between East 33rd and 34th Streets because of its concentration of terriblenesses and virtues. It is congested, dense, torn up, noisy, and lively. Lined by towers and tenements, plied by trucks and fed by tunnels, it's a short walk from offices, hospitals, and trains. Yet we also embraced its frenzy. Our goal was not to impose the serenity of a provincial Dutch city or to streamline the block into anodyne efficiency. New York without friction wouldn't be New York. We aspired to pack all the measures we already knew we should be taking into one vivid frame. An aerial photograph became a platform on which to overlay a possible future city. The result is a real-life I Spy book, filled with details that accumulate into a livable, equitable, safer, and more pleasant place to live. This is no futuristic fantasy of self-sweeping sidewalks or robot-controlled Tesla taxis gliding up at the touch of an app. Instead, we imagined a makeover that could happen now, given urgency and determination. To execute it in permanent, handsome materials would be slow and expensive; a recent project to renovate a stretch of Atlantic Avenue in Brooklyn cost $2.2 million per block. But the DOT has already shown many times that some of this work can be achieved with paint, planters, and boulders. Getting the first draft done matters more than making it perfect and perennial.

Our efforts yielded two big lessons. The first is that every improvement is a trade-off. Protecting bus lanes with concrete barriers, for example, would keep cars out, but it would also keep limited-stop buses from passing local ones. Our street incorporates a possible set of compromises. The second is that even simple tweaks imply a far-reaching organizational overhaul. Enclosed trash bins would push the Department of Sanitation to update some of its trucks and pickup procedures. New regulations and speed limits mean enforcement, and thus money, manpower, and -- most important -- a sense of common purpose.

New Class of Drug Reverses Paralysis In Mice (ibtimes.com) 66

An anonymous reader quotes a report from International Business Times: US scientists have developed a new form of drug that promotes the regeneration of cells and reversed paralysis in mice with spinal injuries, allowing them to walk again within four weeks of treatment. The research was published in the journal Science on Thursday, and the team of Northwestern University scientists behind it hope to approach the Food and Drug Administration as early as next year to propose human trials. [Northwestern's Samuel Stupp, who led the study, and his team] used nanofibers to mimic the architecture of the "extracellular matrix" -- a naturally occurring network of molecules surrounding tissue that is responsible for supporting cells. Each fiber is about 10,000 times narrower than a human hair, and they are made up of hundreds of thousands of bioactive molecules called peptides that transmit signals to promote nerve regeneration. The therapy was injected as a gel into tissue surrounding the spinal cords of lab mice 24 hours after an incision was made in their spines.

The team decided to wait a day because humans who receive devastating spinal injuries from car accidents, gunshots and so on also experience delays in getting treatment. Four weeks later, mice who received the treatment regained their ability to walk almost as well as before the injury. Those left untreated did not. The mice were then put down to examine the impacts of the therapy on the cellular level, and the team found dramatic improvements to the spinal cords. The severed extensions of neurons called axons regenerated, and scar tissue that can act as a physical barrier to regeneration was significantly diminished. What's more, an insulating layer of axons called myelin that is important in transmitting electric signals had reformed, blood vessels that deliver nutrients to injured cells had formed, and more motor neurons survived.

A key discovery by the team was that creating a certain mutation in the molecules intensified their collective motion and heightened their efficacy. This is because receptors in neurons are naturally in constant motion, Stupp explained, and increasing the motion of the therapeutic molecules within the nanofibers helps connect them more effectively with their moving targets. The researchers in fact tested two versions of the treatment -- one with the mutation and one without -- and found that mice that received the modified version regained more function. The gel developed by the scientists is the first of its kind, but could usher in a new generation of medicines known as "supramolecular drugs," because the therapy is an assembly of many molecules rather than a single molecule, said Stupp. According to the team, it is safe because the materials biodegrade within a matter of weeks and become nutrients for cells. Stupp said he hopes to rapidly move direct to human studies next without the need for further animal testing, such as on primates.

Engineers Grow Pancreatic 'Organoids' That Mimic the Real Thing (mit.edu) 8

Researchers from MIT have developed a new way to grow tiny replicas of the pancreas, using either healthy or cancerous pancreatic cells. They believe that their "specialized gel" could also be useful for studying lung, colorectal, and other cancers, including how potential cancer drugs affect tumors and their environment. The findings have been published in the journal Nature Materials. MIT reports: Using a specialized gel that mimics the extracellular environment surrounding the pancreas, the researchers were able to grow pancreatic "organoids," allowing them to study the important interactions between pancreatic tumors and their environment. Unlike some of the gels now used to grow tissue, the new MIT gel is completely synthetic, easy to assemble and can be produced with a consistent composition every time. The researchers have also shown that their new gel can be used to grow other types of tissue, including intestinal and endometrial tissue. [...] About 10 years ago, [Linda Griffith, the School of Engineering Professor of Teaching Innovation and a professor of biological engineering and mechanical engineering, and her lab] started to work on designing a synthetic gel that could be used to grow epithelial cells, which form the sheets that line most organs, along with other supportive cells.

The gel they developed is based on polyethylene glycol (PEG), a polymer that is often used for medical applications because it doesn't interact with living cells. By studying the biochemical and biophysical properties of the extracellular matrix, which surrounds organs in the body, the researchers were able to identify features they could incorporate into the PEG gel to help cells grow in it. One key feature is the presence of molecules called peptide ligands, which interact with cell surface proteins called integrins. The sticky binding between ligands and integrins allows cells to adhere to the gel and form organoids. The researchers found that incorporating small synthetic peptides derived from fibronectin and collagen in their gels allowed them to grow a variety of epithelial tissues, including intestinal tissue. They showed that supportive cells called stromal cells, along with immune cells, can also thrive in this environment.

In the new study, Griffith and [Claus Jorgensen, a group leader at the Cancer Research UK Manchester Institute] wanted to see if the gel could also be used to support the growth of normal pancreatic organoids and pancreatic tumors. Traditionally, it has been difficult to grow pancreatic tissue in a manner that replicates both the cancerous cells and the supporting environment, because once pancreatic tumor cells are removed from the body, they lose their distinctive cancerous traits. Griffith's lab developed a protocol to produce the new gel, and then teamed up with Jorgensen's lab, which studies the biology of pancreatic cancer, to test it. Jorgensen and his students were able to produce the gel and use it to grow pancreatic organoids, using healthy or cancerous pancreatic cells derived from mice. "We got the protocol from Linda and we got the reagents in, and then it just worked," Jorgensen says. "I think that speaks volumes of how robust the system is and how easy it is to implement in the lab."

Fans Ask Questions After First Trailer Released for 'The Matrix Resurrections' (theguardian.com) 140

Moviegoers know that the Matrix trilogy's finale "heavily hinted that our hero will be back at some point in the distant future," writes the Guardian.. "Now he is..."

But does the first three-minute trailer for the soon-to-be-released sequel The Matrix Resurrections suggest Keanu Reeves' "Neo" character has been wiped from existence? In his place is a beardy, incredibly well-aged fiftysomething who looks a bit like John Wick, or possibly that brooding weirdo from The Gift. He meets Carrie-Anne Moss's Trinity in a coffee shop, but fails to recognise her despite all their adventures down the digital rabbit hole. Later he's seen training in what appears to be a dojo with Yahya Abdul-Mateen II's unnamed character, who appears to be fulfilling the Morpheus role of martial arts mentor and guide to the Matrix. Is Abdul-Mateen playing a younger version of the human resistance leader, and if so couldn't they just have digitally de-aged him, given the entire movie probably takes place inside Adobe After Effects anyway?

The teaser poses further questions. Why is Neo taking blue pills as medication? Does this signal the new Neo's willingness to succumb to the virtual world that keeps him blissfully ignorant of the horrifying reality? And if so, what's been going on — didn't the pesky machines promise to free all humans from the Matrix...?

The great thing about Matrix movies is that all usual rules of film-making continuity can be easily placed to one side. Reality can be shifted and reconfigured at every opportunity in the interest of entertainment. This is like the bit in Doctor Who where one Time Lord's face morphs into the next. For all we know, Reeves could be playing the Mad Hatter and Moss a giant pot plant who just appears to be a human being...

There could be a genuinely fascinating reason why Neo and Trinity are back and ready to kick machine ass once again. We won't know for sure until just before Christmas, when the movie hits cinemas.

ABC News notes the new film "also stars returning Matrix co-star Jada Pinkett Smith, features series newcomers Jessica Henwick from Iron Fist, Christina Ricci, Mindhunters star Jonathan Groff, and Priyanka Chopra Jonas." Though as IndieWire points out, there's no sign (yet) of the original Morpheus, Laurence Fishburne.
